The turret is fully rotatable, You think i should go with a bigger gun?I kinda like that gun there is an off chance that I can mount four of them on the turret Or have a gun similar to the mm chain gun used in the Bradley assault vehicle I am defiantly making a missel system similar to that of a BMP's

DOUBLE TAP! If it doesn't die after a first shot shoot it again, repeat ... anything over a full magazine isn't meant to be dead!

And another 6 outside, if you keep the ladders! The full-plate sideskirt will protect the wheels better, but having 6 of them makes a redundant enough system that you could afford to lose one in the heat of battle.
